Local replacement esophagoplasty in children with esophageal stenosis

Abstract

Objective: to evaluate the surgical treatment outcomes of esophageal stenosis using local replacement esophagoplasty in children.
Material and methods. From 2004 to 2016 local replacement esophagoplasties were performed in 15 children aged from 3 to 15 years in the pediatric surgery departments of O.O. Bogomolets National Medical University. In 13 children colon patch for esophagoplasty was used and segmental colon insert was used in 2 patients. 12 patients had corrosive esophageal stenosis and the rest 3 children had peptic stenosis.
Results and discussion. The treatment outcomes analysis of 13 cases showed a smooth postoperative period. In 2 patients there was a need for preventive balloon dilation of the postoperative zone during the period from 1 to 6 months. During the long-term follow-up, which was from 1 to 13 years, in 12 of 13 children who were operated using colon patch the epithelization of stenotic zone and absence of its inflammatory changes was noted. In one case the resection of pseudodiverticulum of the colon transplant was performed 36 months after esophagoplasty with the good postoperative results. In one child with colon patch and in one child with segmental colon insert the postoperative stenosis as result of anastomotic leakage was formed and required the total esophageal replacement after 9-12 months.
Conclusions: Local replacement esophagoplasty is an effective surgical method for treatment of esophageal stenosis in children. Indications for these operations are local esophageal stenosis, which cannot be successfully treated using conservative and instrumental methods along with the preserved function of the upper and lower esophageal sphincters The privilege should be given to the colon patch esophagoplasty due to the preservation of metasympathetic esophageal innervation and the possibility of epithelization of the stenotic area in the long-term period.
